If your sedum roof is still looking a bit red or thin, now is the time to give it a bit of fertilizer. We recommend Osmocote which is a slow release fertilizer with controlled amounts of all the critical nutrients for your roof. Just give it a light sprinkle of about 50g/m2. Our 1kg bags are about right for a 20m2 roof. There is no need to water it in but as we are pretty much in a drought situation already a bit of a soaking would do no harm if we dont see any rain soon.
